Too much coffee?

Is there a good rule of thumb for this? I am not drinking it to the point that I have so many jitters that I can not function, but it does worry me a little with my caffeine obsession (almost). How much is too much in a days time?

Hi cherry! To answer your question, you should decide first - what is too much for yourself?For me, it is more than 4 cups per day+drinking coffee late at night. When I face this kind of situation, I feel like I'm exhausted and powerless. I say stop to myself and quit drinking it for several days - till I get complete recovery of my health

I have never been one that has ever had too much coffee. I can even drink coffee at night and not have a problem with it keeping me up. I am sure my doctor would probably have a fit if she knew how much I drink but I love it, I love the taste, and I am not gonna give it up!
